AGETYLENE-GAS GENERATOR.

Driginal No. 1,569,722, dated January 12, 1926, Serial No. 704,834, filed April 7, 1924. Application for reissue filed August 6, 1927. Serial No. 211,242.

invention relates to acetylene gas ge erators and has for its object the provision of a generator so constructed and arra d asto be automatically self adjusting in t e matter of pressure so that a uniform flow at a certain predetermined pressure may be had.

Another object is the provision of a generator provided with means whereby the generation may be accelerated, retarded or out oif at will with the utmost case.

A further object is the provision of a device of this character constructed and arranged to use carbide in cake form, a magazine bein provided wherein a large quantity may stored and automatically fed to the water whereby the device will be capable of prolonged use without replenishing the supply of material. j

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, use and control, positive in action, eflicient durable in. service and a general improvement in the art. I

With the above and other objects and advanta in view the invention [consists in the etails of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which: p

Figure 1 is a sideelevation off the device partly broken awe and in section.

Fig. 2 is a top p an view.

"Figure 3 is a central longitudinal section.

Fi re ,4 is a cross section on the line 4-'4 of Figure 1. p

Figure 5 is a cross section on the line 5--5 of Figure 3.

Figure 6 is a plan view of they magazine cover.

Referring more particularly to the draw.- ings the numeral 10 designates an upright elongated tank of suitable size and shape, the size depending of course on the charactor of the work in which the generator to be used. Within this tank and rojecting considerably above the top thereo is a shell 11 formed near its upper end with an mwardly extendin ledge 12 for a purpose to be described. T e to of the tank 10 is con nected with the she 11 by a wall 13 in which is located a vent valve 14 for a urpose to be described. The lower'end o the shell 11 extends considerably down into the tank 10, and is flared outwardly as indicated at 15. The tank 10 is designed tocontain water to the level indicated by the line 16 and at this level is provided a drain valve 17 so that after the tank is filled with water 1t may be permitted to drain out to the proper level as indicated after whichthe valve'l? would of course very bottom of the tank is a drain valve 18 so that the water may be drawn out when desired. The space 19 between the tank 10 and shell 11 is used. for confining pressure, and when the device is first started contains only air under pressure.

Mounted at one side of the upper portion of the shell is a filtering device including an elongated casing 20 into the lower end of which leads a pipe 21 communicating with the interior of the shell, and leading from the top of this casing is an outlet pipe 22 provided with a control valve 23. The filtering medium may conveniently be hair indicated at 24, though it is obvious that some other material may be used if preferred. Interpos'ed in the pipe 22 is a T 25 to which is connected a pipe 26 connected with the tank 10 at the wall13 thereof and communicating with the compartment 19. Inthis pipe 26 is a control valve 27. y The numeral 28 represents an elongated ma azine which has a cage bottom 29 and which contains carbide cakes indicated at 30. This magazine is arranged within the shell 11 andis formed with an outstand ing flange 31 which rests upon the ledge 12. The length of this magazine is such that the "lowermost cake therein will be about one-third submerged in the water when the latter is at the level indicated by the line 16. The magazine is of considerably less diameter than the shell 11 so as to provide an annularspace 32 through which the gas generated may rise. The upper end of the magazine is closedby a cover 33 having a finger hold 34 and this cover is held in place by a cap plate 35 engaged upon the upper end of the shell and held by studs 36. For agitating any sludge which accumulates in the bottom of the tank, I provide a stirrer 37 on the lower end of a rod 38 which is journaled in a step bearing 39 and through a packed bearing 40 in the wall 13, the upper end of this rod terminating in a crank handle41.
